What to Look for in the Best Fillet Knives

Now you’ve got a list of the best fishing fillet knives to choose from. How do you make your pick? There are a few different things you’ll want to keep in mind to help you make a decision.

1. Blade Length

The average multi-use fillet knife blade is around 7 inches long. This length is perfect for those who enjoy the occasional fish dinner adventure, but won’t be filleting fish regularly.

If you are filleting more frequently, you’ll probably want to be more specific about your blade length. Different types of fish require different blade lengths. You can choose the blade length best suited for the species of fish you work with most often. Additionally, you can collect a range of blade sizes if you’re liable to process different kinds of fish at any given time.

2. Blade Construction

A good fillet knife needs to be flexible, strong, and thin enough to slide between toothpick bones and cleave away unnecessary skin in one piece. The angle of the blade’s sharp side (called the “edge bevel”) varies from knife to knife, but for fillet work, the ideal edge bevel is between 12 and 17 degrees.

You’ll also need to consider blade retention, aka the blade’s ability to stay sharp over time and use. You can always sharpen your knife if it gets dull, but it can get tedious for the frequent fish filleter.

3. Electric vs. Traditional

Electric fillet knives use battery or plug-in power to move serrated blades back and forth. The movement makes it extremely easy to carve through the fish and get the fillets out, making them the knife of choice for those working with high volumes of fish in a single sitting. They’re also a popular choice with less-experienced filleters who don’t have the time, patience, or desire to learn the ways of the traditional fillet knife.

However, electric fillet knives aren’t nearly as flexible as traditional knives. It’s much harder to do more delicate fillet work, like removing rib bones, with an electric knife over a traditional one. Professionals usually have both styles in their culinary arsenal. They will use the electric for less-delicate species to free the fillet from the body of the fish, and then turning to the traditional blade for the detail work.

4. Fillet Knife Handle

Handles can be made of everything from metal to wood to plastic, and come with all kinds of ergonomic curves. The best handle shape is really up to the individual user. Every hand and grip style is different, so you’ll have to decide which is most comfortable for you.

Regardless of handle type, you will need to consider blade tang. To ensure the blade is strong enough, the knife should have a full tang and rivets on the handle every inch or so. “Full tang” means the blade goes the entire way down into the handle. “Rivets” are just studs that secure the tang inside the handle to the handle itself. They look like little metal circles along the blade handle.

5. Other Considerations

Some fillet knives are dishwasher-safe, to reduce the clean-up routine, but others have to be washed by hand. Fillet knives also come in in different colors and different aesthetics. Electric fillet knives can be corded or battery-powered and are sometimes heavy and cumbersome.
